(eaamn UNDER m A01. 0] ICE 8, 1883, A SLIIHDED APRIL 80, 1928; 370 0. G.757) The invention described herein may be manufactured and used by orfor the Government for governmental pu oses, without the payment to usof any roya ty thereon.

This invention relates to a camera mount- The purpose of the inventionis to provide a camera mountin wherein the camera is capable of bodilydis lacement due to inertia when a vehicle in which the camera iscarried undergoes a change in direction. The field of view of the camerais thereby subject to variations and produces a film or image recordshowing changes in environment that are illustrative of actualconditions as presented to an occupant of the vehicle. When the film ispresented on a screen an impression of reality is conveyed to theobserver.

With the foregoing and other objects in view, the invention residesinthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it bein understood thatchanges in the precise em odiment of the invention herein disclosed maybe made within the scope of what is claimed without departing from thespirit of the invention.

A practical embodiment of the invention is illustrated in theaccompanying drawings, wherein:

Fig. 1 is a view in side elevation of an airlane equipped with thecamera mounting ibrming the subject of the invention;

Fig. 2 is a detail view in side elevation, parts being in section, ofthe mounting;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2; and

Fig. 4 is a sectional view on the line 44 of Fi 2.

Re erring to drawings by characters of reference:

There is shown in Fig. 1 an airplane fuselage 5 having the front seat orcockpit 6 and a rear seat or cockpit 7. For the purpose of the followingdescription the pilot of the airplane occupies the rear seat andoperates the controls during flight. I

Over the front seat there is a camera mounting A arranged to support acamera B at the approximate position of the head of an occupant of theseat so that the focal lens 8 of the camera is representative of theeyes of theoccupant. The camera is trunnioned in a gimbal ring 9 whichin turn is trunnioned in a support 10 in the conventional manner. IDepe-ndin from the camera is a bar 11 which is hefd by a plurality ofsprings 12, four being shown and preferably corresponding with andarallel to the trunnions. The outer ends of t e springs are confined byseats 13 threaded in the support 10.

The support 10.is rotatably mounted on a fixed base 14 in such aposition that the camera is. normally perpendicular to the longitudinalaxis of the airplane and the line of si ht 15 re resents the line ofsight that woul exist or the occupant of the seat. Due to the inertia ofthe camera any change in direction of the airplane will produce amovement of the camera corresponding to the movement of an occupant inthat position in the airplane. The line of sight or the field of viewofthe camera will thereby be changed and record a variation in thenormal environment. When the film is projected on to a screen, animpression of reality will be conveyed to the observer.

A film of this character is useful in giving a student pilot the feel ofthe air without actually flying and is to be used in conjunction with aset of training controls operated by the student when viewing thepicture.

Under certain circumstances such as in formation flying it is desirableto shift the line of sight laterally to simulate a correspondingmovement of the line of sight of the pilot and to this end the support10 is provided with gear teeth 16 meshing with a driving gear 17 whichis under the control of the pilot in the rear seat.

We claim:

1. In combination with a vehicle, a support therein, a gimbal ring onthe support, a camera trunnioned in the gimbal ring with its field ofview corresponding to the field of view of an occupant in normalposition in the vehicle, a depending member on the camera, springsacting on the depending member from different points to maintaintherein, a gimbal rin ron the support, a
